dextro,laevo-tryptophan
propionic acid, 2-amino-3-indol-3-yl-
 
Notes:
Dietary supplement, nutrient Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet. Only the L-stereoisomer of tryptophan is used in structural or enzyme proteins, but the D-stereoisomer is occasionally found in naturally produced peptides (for example, the marine venom peptide contryphan).
